Question

$$3x(5+2y)-8y(5-10x)$$

Evaluate

$86xy+15x-40y$

Solution Steps

Use the distributive property to multiply $3x$ by $5+2y$.

$$15x+6xy-8y\left(5-10x\right)$$

Use the distributive property to multiply $-8y$ by $5-10x$.

$$15x+6xy-40y+80yx$$

Combine $6xy$ and $80yx$ to get $86xy$.

$$15x+86xy-40y$$

Expand

$86xy+15x-40y$
